Someone who acts like someone they're not, but they don't realize that there being fake, basically a loser trying to fit in. They usually buy ‘trendy’, fake- fancy stuff to look better for people and acts like the majority.

The girl wanted to look like a boy, as long as the boy was an athlete or an astronaut and not a loser. If the boy she was trying to look like was a loser, she would turn into a coward and let a male look like the loser. All of that could be avoided by being yourself, instead of living your life as a poser.

A dedicated fan of Lego, retro video games, and vinyl during lockdown but has since went back to his craft beer flights, indoor axe throwing, and pickleball.
"Dakota is such a COVID poser. As soon as lockdown lifted, he went right back to being a gentrified sheep"

The Cinderella poser lives in a nicer house than her siblings, comes from a bigger house than her siblings, and has been to every one of her childhood friends' weddings, yet still always claims to be an underdog whenever there is a sports game or something she is desperate to win (with her spoiled rotten sense of injustice and disadvantages in life) . She claims that she was an underdog to the people she claims were in line in front of her/in her way, when in reality they weren't in line for anything, they weren't trying to become royalty (rich and powerful) like she was.

If a guy has convinced people he's Italian (such as an actor in a movie), but he's not really Italian, no matter how believable the guy is, he's not authentic, so he's a poser.
The poser had convinced people that he/she was from hell and that he/she was hell, but since there was no hell, he/she was just another otherwise obscure poser.

The narcissistic girl saw a badass shark when she looked in the mirro and thought that everyone else could see in her what she saw in herself, but they were looking at her spirit and not her appearance, and all they saw was a plain and bossy poser that everyone had tried to keep from drowning her entire life.
